Consider a quantum system wtih three states, and a hamiltonian given by 0 3 4 with ε a small parameter and vo and η are constants. we assume η 0. (a) write the eigenvalues e and eigevectors in0)) of the unperturbed hamiltonian (c = 0) for n = 1,2,3. (b) find the three first-order energies, e for n 1,2,3, due to the perturbation e. (c) find the first-order correction to the three eigenstates, in(1), with n = 1,2,3 ( d set vo = 1 (in units of energy) and η = 0.5. plot the three energies ) and the three energies en) for small e, with n = 1,2,3. (e) set vo-1 and η = 0.5. plot the three components of ln(iy for small ε for n = 1. in the plots, you need to decide how far to plot in ε, since ε must be a small parameter.
